A truck driver in Peru damaged the 2,000-year-old Nazca Lines, after officials said he ignored warning signs and drove over a portion of the UNESCO World Heritage Site.

The Nazca Lines are large designs that were scratched into the ground’s surface between 500 B.C. and A.D. 500 on a coastal plain south of Lima. UNESCO calls the site one of the “greatest enigmas” of the archaeological world. They cover about 290 square miles and depict creatures, plants and imaginary beings, as well as geometric designs.
